Abstract
A trajectory correction scheme of pulse jet based on direct force control was brought forward. The starting time selection principle was analyzed. The velocity vector tracing guidance law in horizontal plane was deduced, and the impact point forecast guidance law in the vertical plane was introduced. The fire logic of pulse jets was analyzed, and the control diagram was provided. By numerical simulation, the control scheme was validated. The calculation indicates that the circular probable error reduces to 42 m from 131 m, and the fire accuracy is improved effectively.
